The wires going to the coil are hooked up the same as they were before, and it worked before. I'll double check everything. I know I only have 2 wires hooked directly to the + side of the coil; the red one going to the distributor, and the wire that was originally hooked the the + side of the original coil.

I checked for voltage at the coil +, and it's getting power with the key on only, which I'm pretty sure is how it's supposed to be. I'm going to check all grounds for the 10th time, and check those wires at the bulkhead. The instructions that came with my MSD didn't have that detailed of a diagram.
